Re: Exhaust port crack.... need help!
Matt,
this is a good candidate for the block sealers available in a bottle.
the active ingredient is sodium silicate, or also known as liquid glass.
being this is a low pressure area and in the hot exhaust it will seal quite well.
depending on the water pump you have, you may need to reseal it if it starts to leak.
